A question about instruction during self-paced reading

[Hyeonah]

Hi Ting,

I made an instruction as an image ("press_inst_pic") and paired this with self-paced reading.
For example,

"Text2B_inst": {
"type": "basic",
"stimuli": [
{"which":["press_inst_pic","Text2B"],"location":[2,5]}
],
"responses": [],
"auto_advance": true
},

This looks fine to me, but I have one more issue that I'd like to ask for your help with.
If I l switch the location of the instruction image and the reading so that the instruction image can appear at the bottom (5) and the reading appears at the top (2) like

"Text2B_inst": {
"type": "basic",
"stimuli": [
{"which":["Text2B", "press_inst_pic"],"location":[2,5]}
],
"responses": [],
"auto_advance": true
},

The instruction image disappears and I can only see the blank screen.
Is there any way that I can deal with this? Thank you so much!
